What can be made from woods?

Answer 1

Any strong wood. In the US, softwood plywood is generally made from Douglas fir or southern yellow pine. Most hardwood plywood is "veneer core." This means they make sheets of plywood from poplar--an inexpensive hardwood but plenty good for plywood--then put veneers of a more expensive hardwood on both sides of the finished sheet. If you run into oak "marine plywood" all the plies are made from oak. Oak is extremely hard to make into good plywood cores because it is so hard, so oak marine plywood is really expensive.
